A question on Pendulum experiment
#15
I have yet another question for pendulum experiment.  I'm using is as a sort of tutorial on how phyphox file/experiment work - so it is entirely possible I do not understand all of it.
Toward the end of that pendulum experiment there's this code:
"
        <average>
            <input as="buffer" clear="false">anyGyr</input>
            <output as="average" clear="false">avg</output>
            <output as="stddev">amplitudeSkewed</output>
        </average>
[...]
        <divide>
            <input as="dividend" clear="false">amplitudeSkewed</input>
            <input as="divisor" clear="false">frequency</input>
            <input as="divisor" clear="false">frequency</input>
            <output as="quotient">amplitude</output>
        </divide>
"
so it seems it is calculating average of gyroscope readings (angular velocity), and its standard deviation.  And then uses stdDev/(frequency*frequency) to get amplitude.
frequency is the calculated frequency of the pendulum.  What does 'amplitude' calculated that way represent?
